No. 858,369 8Claims. (Cl. 240-112) This invention relates to a novel lamp forproviding illumination, and more particularly to a lamp of uniqueornamental appearance which is so constructed that all light raysemitted therefrom are reflected.

Another object of the invention is to provide a lamp structure whereinthe light source is completely concealed.

Still another object of the invention is toprovide a lamp composed ofsections capable of being readily separated for replacement of the lightsource.

Another object of the invention is to provide a lamp having a pluralityof sides each provided with an opening through which the reflected lightrays from the concealed light source of the lamp are emitted.

Various other objects and advantages of the invention will hereinafterbecome more fully apparent from the following description of thedrawings, illustrating a presently preferred embodiment thereof, andwherein:

FIGURE 1 is a side elevational view of the lamp;

FIGURE 2 is an enlarged fragmentary side elevational view of a portionof the lamp;

FIGURE 3 is a horizontal sectional view through the lamp, takensubstantially along a plane as indicated by the lines 33 of FIGURES 2and 4;

FIGURE 4 is a fragmentary vertical sectional view taken substantiallyalong a plane as indicated by the lines 44 of FIGURES 3 and 5;

FIGURE 5 is a top plan view of the intermediate section of the lamp,with the top section removed, and

FIGURE 6 is a horizontal sectional view taken substantially along aplane as indicated by the line 66 of FIGURE 4, partly broken away.

Referring more specifically to the drawings, the ornamental lamp in itsentirety is designated generally 8 and is composed of a lower section 9,an intermediate section 10 and an upper section 11. The lamp 8 ispentagon shaped, as viewed from above, but could have more or less thanfive sides.

The bottom section 9 includes a substantially flat five sided top wall12 which is supported by five corresponding depending walls 13 which aresuitably secured to or formed integral with the five straight edges ofthe top wall 12 and which extend downwardly and inwardly therefrom. Saiddepending walls 13 taper in width toward their lower ends and are joinedto one another along their downwardly converging side edges, so that thefive walls 13 form an inverted truncated pyramid. A flat rigid plate 1-4has the central portion of one face thereof suitably secured, as bywelding, as seen at 15, to the truncated end of said inverted pyramidportion. The plate 14 forms the base for the lamp and is likewisepreferably pentagon shaped and somewhat smaller than the top plate 12. Aplurality, preferably five pins 16 are secured in and extend upwardlyfrom the wall 12 and a spacing sleeve 17 is mounted on each pin 16. Thepins 16 are spaced from the corners and edges of the plate 12.

The intermediate lamp section 10 includes a pentagon shapedsubstantially flat bottom plate 18 and a corresponding top plate '19.The plate 18 has a short depending wall which is likewise pentagonshaped and Patented July 25, 19 1 ICC extends downwardly from the fiveedge portions thereof, and the top plate 19 has an upstanding wall 21,corresponding to the wall 20. The plates 18 and 19 are each providedwith a central opening 22 and pin receiving openings 23. The pinreceiving openings 23 of the bottom plate 18 are positioned to receivethe upper ends of the pins 16 when the plate 18 is located directlyabove and in alignment with the plate 12. The intermediate section 10 isconnected to the bottom section 9 by the pins 16 and the intermediatesection is supported by its bottom plate 18 resting on the spacingsleeves 17. When thus disposed, the wall 20 extends between the edges ofthe plates '12 and 18. The plates 18 and 19 are also provided with aplurality of vent openings 24, which are spaced from the openings 22 and23 thereof and which are preferably somewhat smaller than the centralopening 22, as best seen in FIGURE 5.

The intermediate section 10 includes an inner bottom plate 25 and aninner top plate 26. The inner bottom plate 25 has a central portionspaced substantially from the plane of the plate 18 which is providedwith an opening 27 which aligns with the opening 22. The plates 25 and26 are also pentagon shaped and the marginal portion 28 of the plate 25rests upon and is secured to the marginal portion of the plate 18, inany suitable manner, as by welding, as seen at 15 in FIGURE 4. The plate25 has five portions 29 which slope downwardly and outwardly from thecentral opening 27 of said-plate to its marginal portion 28, and whichsloping portions 29 coincide with the five straight edge portions of theplates 18 and 25. The plate 26 corresponds with the plate 25 except thatit is inverted so that the portions 29 thereof slope downwardly andinwardly from the marginal portion 28 to the central opening 27, and theinner top plate 26 is secured to the top plate 19 in the same mannerthat the plate 25 is secured to the plate 18.

The intermediate lamp section 10 includes five corresponding verticalpartition walls 30 which are equally spaced from one another, as seen inFIGURE 3, and which have downwardly and inwardly inclined upper edgessecured to the inner top wall 26 and upwardly and inwardly inclinedbottom edges which are secured to the inner bottom wall 25. The inneredges of the walls 30 terminate adjacent the openings 27, as seen inFIGURES 3 and 4. Each of the walls 30 extends toward one of the fivecorners of the pentagon shaped lamp, as seen in FIGURE 3, from its inneredge, and each of said walls or partitions is preferably formed of twoplies having outer portions 31 which are flared away from one anotherand inner portions 32 which are secured together in abutting engagement.

The intermediate section 10 includes five corresponding upright cornerposts 33 of angular cross section, as seen in FIGURE 3, corresponding tothe angles formed by the adjacent sides of the lamp. The lower ends ofthe corner posts 33 are secured, as by welding, to the corners of thewall 20 and the upper ends of said corner posts are similarly secured tothe corners of the wall 21. The flared outer edges of the ply portions31 of each wall 30 are secured to the vertical side edges of the cornerpost 33 with which said wall 30 aligns, as clearly illustrated in FIGURE3.

The intermediate section 10 also includes five upright opaque shields 34each of which is disposed between two adjacent partition walls 30 andspaced therefrom. Each shield 34 has pins or studs 35 projecting fromits upper and lower ends. The upwardly extending studs 35 engage in andare secured to the wall 26 and the downwardly extending studs 35 engagein and are secured to the wall 25 for mounting the shields 34 betweenand spaced from said walls 25 and 26 and also between and spaced fromthe partition walls 30, as seen in FIGURES 3 and 4. The shields 34 arespaced equal distances from the center openings 27 and are locatedbetween and spaced from the center openings 27 and the openings 36 ofthe five sides of the intermediate lamp section 10. Each of saidopenings 86 is formed by complementary portions of the walls 20 and 21and two adjacent corner posts 33, as best illustrated in FIG- URE 2.

A conventional double lamp bulb socket 37 is mounted between and securedto the inner edges of the walls 30 and may be secured to the inner edgesof said walls by a press fit engagement or by additional solderconnections 15. The socket 37 is disposed between and spaced from thewalls 25 and 26. Lamp bulbs 38 are mounted in and project from theopposite upper and lower sides of the socket 37 and are disposed betweensaid socket and the openings 27. The openings 27 are of a largerdiameter than the lamp bulbs 38 and are of the same diameter as theopenings 22, so that the lamp bulbs 38 can be removed and replacedthrough the openings 22 and 27 when the lamp sections are disconnected,as will hereinafter be described. The inner edges of the partition walls30 combine with inner ends of the sloping wall portions 29 to form inneropenings between the shields 34 and the light bulbs 38.

The upper section 11 comprises a bottom Wall 39, corresponding to thewall 12 and five upwardly and inwardly converging walls 40,corresponding to the walls 13. The walls 40 form a truncated pyramid, asseen in FIGURE 1. The wall 39 is provided with pins 16, arranged in thesame manner as the pins 16 of the wall 12, and which last mentioned pinsextend downwardly from and are secured to said wall 39 and have spacingsleeves 17 mounted thereon and secured to the pins, beneath the wall 39.Said last mentioned pins 16 engage detachably in the openings 23 of thewall 19 and the last mentioned sleeves 17 rest on the wall 19 fordetachably connecting the top section 11 to the intermediate section andfor mounting said top section thereon. The wall 21 coincides with theedge portions of the wall 39, in the same manner that the wall coincideswith the edge portions of the wall 12.

Electric current can be supplied to the lamp socket 37 in any desiredmanner, as by an electric cord 41 which can extend into the base section9 through an opening 42 in one of the walls 13 and thence upwardlythrough an opening 43 in the wall 12 and thence through the opening 22in the wall 18 and opening 27 of wall 25 to the socket 37. The cord 41can be positioned to extend along the inner edge of one of the walls 30.

It will be readily apparent that light rays from the light bulbs 38 willpass outwardly around the opaque shields 34 between the side edgesthereof and the walls and between the top and bottom edges thereof andthe walls 26 and 25. The walls 30, 25 and 26 are formed of a lightreflecting material so that the light rays from the light bulbs 38 willbe reflected from said walls and outwardly through the openings 36.Thus, none of the light rays will be emitted directly from the lamp 8and all emitted light rays will be reflected. Furthermore, the lightbulbs 38 are completely concealed within the intermediate section 10, asclearly illustrated in FIG- URES l and 2, so that the light source ofthe lamp is not visible.

The upper light bulb 38 can be replaced by merely lifting off the uppersection 11, after which the upper light bulb is removed and replacedthrough the opening 22 of the wall 19 and the opening 27 of wall 26. Thelower light bulb 38 is removed and replaced by lifting the intermediateand top section all of the base section 9 so that said bulb can beremoved and replaced through the opening 22 in wall 18 and opening 27 ofwall 25. Sufiicient slack in the electric cord 39 can be retained in thebase section 9 for this purpose.

Various modifications and changes are contemplated and may be resortedto, without departing from the function or scope of the invention ashereinafter defined by the appended claims.
